ULTRAFLOW® 54
DN150-250
ULTRAFLOW® 54 is a static flow sensor
based on the ultrasonic measuring
principle. It is primarily used as a
volume flow sensor for energy meters
such as MULTICAL®. ULTRAFLOW® 54
has been designed for use in heating
and cooling installations where water
is the heat-bearing medium.
ULTRAFLOW® 54 employs ultrasonic
measuring techniques and micropro-
cessor technology. All calculating and
flow measuring circuits are collected
on one single board, thus provid-
ing a compact and rational design
and, in addition, exceptionally high
measuring accuracy and reliability is
obtained.
The volume is measured using bidirec-
tional ultrasonic technique based on
the transit time method, with proven
long-term stability and accuracy. Four
ultrasonic transducers are used to
send sound signals both against and
with the flow. The ultrasonic signal
travelling with the flow reaches the
opposite transducer first. The time dif-
ference between the two signals can
be converted into flow velocity and
thereby also volume.
A three-wire signal cable is used
to connect ULTRAFLOW® 54 to the
Kamstrup MULTICAL® calculator. The
cable supplies the flow sensor and
also transfers the signal from sensor
to calculator. A signal correspond-
ing to the flow – or more correctly, a
number of pulses proportional to the
water volume flowing through – is
transmitted.
ULTRAFLOW® 54 is available with
internal supply, e.g. if the distance
between MULTICAL® and
ULTRAFLOW® 54 is 10 m or more.
If ULTRAFLOW® 54 is used for other
equipment (e.g. other brands of calcu-
lators), the meter must be fitted with a
galvanically separated output module
and a supply of its own.

Installation
Installation angle of ULTRAFLOW® 54
ULTRAFLOW® 54 can be installed horizontally,
vertically, or at an angle.
ULTRAFLOW® 54 is normally installed horizon-
tally, with the lifting rings oriented vertically. The
ultrasound paths in the flow sensor tube will thus
be vertical, which is optimal in connection with
possible stratification of the medium.
Prior to installation of the flow sensor, the system should be flushed.
Correct flow sensor position (flow or return) appears from the front label of MULTICAL®. The flow direc-
tion is indicated by an arrow on the side of the flow sensor.
Please note: ULTRAFLOW® 54 may be lifted in the lifting rings only.
Pressure stage ULTRAFLOW® 54: PN25
Temperature of medium, ULTRAFLOW® 54: 2…150°C/2…50°C. See marking on label.
Mechanical environment: M1 and M2 (fixed installation with minimum vibration and fixed installation
with considerable or high vibration level respectively). See marking on label.
Electromagnetic environment: E1 and E2 (housing/light industry and industry respectively). See mar-
king on label.
The meter’s signal cables must be drawn at min. 25 cm distance to other installations.
Climatic environment: Must be installed in environments with non-condensing humidity as well as in
closed locations (indoors).
The ambient temperature must be within 5…55°C.
Maintenance and repair: The flow sensor is verified separately and can, therefore, be separated from
the calculator. It is permitted to replace the supply and change the supply type. For battery supply a
lithium battery with connector from Kamstrup A/S must be used. Lithium batteries must be correctly
handled and disposed of (see Kamstrup document 5510-408, ”Lithium batteries - Handling and dispo-
sal”). Other repairs require subsequent reverification in an accredited laboratory.
If ULTRAFLOW® 54 is connected via a galvanically coupled output module, the flow sensor may be con-
nected to a Kamstrup MULTICAL® calculator only.
If other calculator types are connected, ULTRAFLOW® 54 must be fitted with a galvanically separated
output module and a power supply of its own.
Please note: Please make sure that pulse figures of flow sensor and calculator are identical.
The steel tube between flow sensor housing and electronics box must not be disassembled.
At medium temperatures above 90°C (Tmed
90°C) or medium temperature more than 5°C below ambi-
ent temperature (Tmed
Tamb
- 5°C) the flow sensor's electronics box must be mounted via the enclosed
distance piece. Alternatively, the electronics box can be wall-mounted at a distance of minimum 170
mm from the sensor.
In order to prevent cavitation, the back pressure at ULTRAFLOW® 54 must be min. 1.5 bar at qp
and min.
2.5 bar at qs
. This applies to temperatures up to approx. 80o
C.
When the installation has been completed, water flow can be turned on. The valve on the inlet side
must be opened first.

Straight inlet ULTRAFLOW® 54
ULTRAFLOW® 54 requires neither straight inlet nor outlet in order to fulfil the Measuring Instruments
Directive (MID) 2004/22/ EC and EN 1434:2007. A straight inlet section will only be necessary in case
of heavy flow disturbances before the meter. We recommend that the guidelines of CEN CR 13582 are
followed.
Optimal position can be obtained by taking the below-mentioned installation methods into considera-
tion:
A. Recommended flow sensor position.
B. Recommended flow sensor position.
C. Unacceptable position due to risk of air build-up
D. Acceptable in closed systems.
Unacceptable position in open systems due to risk of air build-up in the system
E. A flow sensor ought not to be placed immediately after a valve, with the exception of block valves
(ball valve type) which must be fully open when not used for blocking.
F. A flow sensor must never be placed on the inlet side of a pump
G. A flow sensor ought not to be placed after a double bend in two levels.
For general information concerning installation, see CEN report DS/CEN/CR 13582, Heat meter installa-
tion. Instructions in selection, installation and use of heat meters.

Connection to calculator
ULTRAFLOW® 54 and MULTICAL®, galvanically coupled
If ULTRAFLOW® 54 and MULTICAL® are connected via output module (Y=1), ULTRAFLOW® 54 is galvani-
cally coupled with MULTICAL® and is powered via the three-wire signal cable (cable length up to 10 m).
Battery life time in e.g. MULTICAL® 602 is approximately 10 years depending on data communication to
the calculator.
Note: It is not permitted to mount a supply module or battery in ULTRAFLOW® 54.
ULTRAFLOW® 54 → MULTICAL®
11 → 11 GND (Blue)
9 → 9 + 3,6 V (Red)
10 → 10 (Yellow)
When using long signal cables, careful consideration is required in connection with installation. Due to
EMC there must be a distance of min. 25 cm between signal cables and all other cables.
ULTRAFLOW® 54 and MULTICAL®, galvanically separated
If ULTRAFLOW® 54 and MULTICAL® are connected via output module (Y=2 or 3), ULTRAFLOW® 54 is
galvanically separated from MULTICAL®.
Note: Flow info cannot be read.

Cables
ULTRAFLOW® 54 DN150-250, when ordered with MULTICAL®, is delivered with 2.5 m signal cable, optio-
nally 5 or 10 m. The cable is mounted in the ULTRAFLOW® 54 electronics box and in MULTICAL® 6xx.
When ULTRAFLOW® 54 is ordered with MULTICAL® 8xx, the calculator is delivered separately. Hence the
cable is only mounted in the ULTRAFLOW® 54 electronics box.
ULTRAFLOW® 54 DN150-250, when ordered as a separate flow sensor, is optionally available with signal
cable in lengths of 2.5, 5 or 10 m. The cable is mounted in the ULTRAFLOW® 54 electronics box.
If 24/230 VAC supply module is selected, the sensor is optionally available with power cable. The cable
is mounted in the sensor's electronics box from the factory.
